CA3100Y - 100Amp Circuit Breaker

CA3100Y - 100 Amp Circuit Breaker

The CA3100Y molded case circuit breaker is a 3-pole, 100-amp breaker designed for dependable circuit protection in commercial and industrial power distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker provides consistent overcurrent protection at up to 10kA interrupting capacity at 240VAC. Engineered for operation in ambient temperatures up to 40°C, the CA3100Y is suited for panelboards and distribution equipment requiring a properly rated, form-fit-function replacement breaker. With included line-side lugs and a durable molded case housing, this unit is built to last and maintain reliable performance in legacy electrical systems where compatibility and correct ratings matter most.

Whether you are replacing an existing CA frame breaker or maintaining an established power distribution setup, the CA3100Y delivers the amperage, interrupting rating, and physical configuration required for safe and code-compliant operation.
